6. Operational phase: Fuel consumption during the life cycle
During operation, the Audi Q has a high fuel consumption, which makes it a model with high driving emissions. Fuel consumption and emissions depend on the specific model, drive unit and driving style, we cannot estimate any average values:
- Fuel consumption : The average fuel consumption of the Audi Q8 is approximately 10 l/100 km (petrol) or 8 l/100 km (diesel).
- Total emissions during the life cycle (200,000 km) : At estimated emissions 2.4 kg of CO₂ per liter of gasoline or 2.7 kg of CO₂ per liter of diesel represent the total emission approximately 48 tons of CO₂ (petrol) or 43.2 tons of CO₂ (diesel) .
7. Disposal and recycling of the vehicle
After the end of the vehicle's life cycle, it comes to its disposal and recycling, which includes the disposal and processing of individual materials. Some parts, such as aluminum and steel, can be recycled, which partially offsets the emissions associated with the production of new materials.
- four emissions during disposal and recycling of vehicles : Disposal and recycling of one vehicle contributes to the carbon footprint of approx 0.5 – 0.7 tons of CO₂ .
The total carbon footprint of the production and life cycle of the Audi Q8
Based on the individual phases of production and operation, we can estimate the total carbon footprint of the Audi Q8 throughout its life cycle.
| Phase | Emissions (in tons of CO₂) |
|---|---|
| Energy production for the factory | 2 – 4 |
| Production of materials and components | 4.4-5 |
| Transport of raw materials and components | 0.5-1 |
| Painting and finishing | 0.6 – 1.2 |
| Logistics of finished vehicles | 0.3-0.5 |
| Operation (200,000 km) | 43.2 – 48 |
| Disposal and recycling | 0.5-0.7 |
| Total issue | 51.5 – 60.4 |
Summary and mitigation
The total carbon footprint of the Audi Q8 over its life cycle amounts to approx 51.5 – 60.4 tons of CO₂ . Of this, the largest share is emissions during the operation of vehicles, which correspond to almost 80 % of the total number of emissions. The higher carbon footprint is due to the size of the vehicle's weight, as well as the fuel consumption typical of vehicles in the SUV category.
Audi and automakers working to reduce these emissions benefits:
- Electrification : Audi introduces electric and hybrid models that maintain emissions during operation.
- Sustainable materials : Using recycled and sustainable materials in the interior and exterior.
- Renewable resources in factories : Transition to energy from renewable sources in plants.
- Reducing the weight of vehicles : Use of lighter materials such as aluminum alloys and composites, which can improve vehicle manufacturing.
These steps can significantly reduce the carbon footprint of vehicle production and operation, as well as contribute to the automotive industry and the industry's environmental impact.
Car manufacturers are facing increasing pressure to reduce the carbon footprint of their products. For large SUVs like the Audi Q8, these challenges are even greater. Below we look at specific measures that car companies, including Audi, are implementing or planning to implement to reduce emissions.
1. Electrification and hybrid technologies
One of the most effective ways to reduce emissions during vehicle operation is electrification. Audi has already expanded its range with fully electric models and plans to transform several of its models into electric hybrid versions in the coming years. In some versions, the Audi Q8 model is also available as a plug-in hybrid, which makes it possible to combine an electric drive with a traditional combustion engine and thereby reduce emissions.
- Plug-in hybrid version : In an urban environment, such a version can run purely on electricity, temporarily reducing CO₂ emissions to zero if it is charged from renewable sources.
- Full electric SUV : Audi is developing new all-electric models that can confirm the carbon footprint not only during operation, but also during production if they switch to renewable sources.
2. Increasing production efficiency and switching to green energy
Switching to renewable energy sources in factories is an important step in reducing the overall carbon footprint of production. Audi is already currently working on reducing emissions from factories through energy savings and the use of renewable resources.
